What's the reason for /run tmpfs?

The reason I love Arch is its "KISS-compliance". The more standard, the more simple -- the better. May I ask for the reason of introducing the /run tmpfs instead of standard /var/run?
Best regards,
/m

PS. To be clear. My question is not: `why is it tmpfs?'. I'm askin': `why /run instead od /var/run ?'

  • When I try to install CS6 Design and Web Premium from a disk I get this message "We are unable to validate this serial number..." What is the reason for this?

    I purchased a disk copy of CS6 Design and Web Premium from a reputable seller last week and when I try to install it with the serial number I got it says "We are unable to validate this serial number for CS6 Design and Web Premium. Please contact Customer Support." What is the reason for this?
    Is the serial number invalid?

    Hi Ned,
    Thanks for the suggestion. I eventually got in touch with Adobe Technical Support and it turned out that my Adobe Application Manager was not the latest version. They downloaded the latest version and installed it and that seemed to solve the problem. I was able to install my CS6 Creative Suite and validate the serial number. All seems to be going well at the moment.

  • What is the reason for query take more time to execute

    Hi,
    What is the reason for the query take more time inside procedure.
    but if i execute that query alone then it excute within a minutes.
    query includes update and insert.

    I have a insert and update query when I execute
    without Procedure then that query execute faster but
    If I execute inside procedure then It takes 2 hours
    to execute.Put you watch 2 hours back and the problem will disappear.
    do you understand what I want to say?I understood what you wanted to say and I understood you didn't understood what I said.
    What does the procedure, what does the query, how can you say the query does the same as the procedure that takes longer. You didn't say anything useful to have an idea of what you're talking about.
    Everyone knows what means that something is slower than something else, but it means nothing if you don't say what you're talking about.
    To begin with something take a look at this
    When your query takes too long ...
    especially the part regarding the trace.

  • How can i get to know what is the reason for implausible meater reading?

    Hi All,
    I am new to this SAP -ISU.
    can any body tell me how can i get the reason for implausible meater reading.
    my requirement is to get the unbilled meters becasuse of unrealibility of meter reader.
    here what i understood is if meater reading is not in a position to bill so it means meater reading may be in implausible state. so i want to know the reason for implausible meater reading so that i get the meters which are not billed because of unreliasility of meter reader.
    in which table these reasons get store.
    if any body knows about these please reply me ASAP.
    Thanks in Advance.

    At the very least, you will receive EXACTLY the same product you sent in.  You may get a newer product.  It's Apple's choice.

  • What's the reason for " 'Writing XMP Metadata' did not complete successfully

    I rightclicked an image and selected "save metadata to file" and got this not-so-very-informative error message. What could be the cause? The file is there and it is not write protected.
    Adobe - what about giving some more information when LR encounters errors?
    Win XP, LR 1.3.1

    While read only is the most likely cause, I have been trying to track down a similar problem which so far I can only equate to the creation time of the file ending in 00.
    For example, I have a file taken at 6/13/2006 1:00:00 PM
    If I do Metadata -> Edit Capture Time...
      and set the time to be 6/13/2006 1:00:01 PM
    Then click twice on the Resolve Conflicts button for Metadata, the second one works.  Both times I tell it to overwrite the metadata on disk.  My assumption is that the data processing logic has issues reading in entries like:
       2006-06-13T13:00:00-08:00
    I would even go so far as speculating it treats them as just the day and drops the hour / minute portion.  The reason for this conjecture is that I stumbled on this issue when exporting images would occasionally have 2006/06/13 12:00AM as the timestamp and when I checked which ones had problems, they all were taken at 00 seconds into the minute.
    Henrik, if you are still having this problem, does the file happen to have a 00 second creation timestamp?  If so, try changing it by a second and I would be curious if you it starts working for you too.
    Cheers,
    John

  • What is the reason for this error? after export part of movie broken

    hi, i cannot find the reason for this strange error that happaned to me for the first time, you can see the outcome here:
    http://picasaweb.google.com/p.cardash/IMovieBug/photo#5164317113276584274
    after exporting in imovie to h264 .mov file, from HDV project, resolution is twisted, plus, the part that was supposed to fit hole screen, is black and sometimes with little graphic errors.
    i tried about 10 times, with different setting, resolutions, and other parameteres.
    after exporting for ipod, everything is ok, in m4v format.
    what is wrong? i use the same method for creating and also for exporting, as in previous projects. i didnt use any new transitions, efects nor titles...
    any thoughts?
    best to You,
    Piotr

    ok, i think that i know where is the problem, but i still dont what is it
    ive copied my file to a new mac with just installed imovie and everything is the same,exactly the same output. so 100% positively the problem is within the particular project.
    i didnt check my mackbook with TT, since i dont have it and dont want to pay i thought its for free
    i`ll try later to figure out what wrong and what part of the project is bad.
    for now, i think i hate imovie again :)) piece of..
    let me know how your case ended.

    either something got damaged when you installed the hard drive or you need to perform a pram reset (other possibilites could have occured, these are the ones I think)

  • What are the reasons for disabling the saving of data in a PDF?

    I seem to have had more than my share of encounters lately with PDF files that have editable fields but have their data saving capability disabled.
    In some of these situations this has been an absolutely maddening inconvenience.
    When I attempt to bring this to the attention of whomever's responsible I get brushed off.
    One person's response was: Actually the majority of the PDF forms I have are Adobe reader and you cannot make changes electronically at all.  The reason for this is to make sure that the documents are not altered in any way.  The <companies creating the PDFs> must make sure that changes are not being made to their forms. 
    I just don't understand that.  How is entering and saving data 'altering' a PDF?
    Is this just bone-headed bureacracy, an urban legend, or is there some fundamental practical matter I am not aware of?

    Saving a filled-in form has always been disallowed with Adobe Reader, formerly known as Acrobat Reader. Though there are a few exceptions...
    History lesson:
    Forms features were first introduced in Acrobat 3. As you might imagine, a number of folks wanted to be able to save filled-in forms using Acrobat Reader. Since this functionality simply was not a feature of Reader, it was not possible. If you wanted to save a filled-in form, you needed to use Acrobat (Exchange).
    Upon recognizing the potential market for a product that they could sell, Adobe developed and released Acrobat Business Tools, which was a version 4 product. It was positioned between Reader and Acrobat, was reasonably priced, and allowed users to save filled-in forms, apply digital signatures, and add comments. Unfortunately, this was marketed poorly and did not achieve commercial success.
    The next iteration was a similar product named Acrobat Approval, which was a version 5 product. It too could save a filled-in form, but was in some ways more limited than Business Tools, and suffered a similar fate. That is, it was not a market success. It was however distributed for free to US taxpayers on the IRS tax products CD-ROM.
    The next idea from Adobe - which was a good one - was to provide for a means of embedding usage rights in a PDF document. These rights would allow Reader to do things it normally would not be able to do, such as saving a filled-in form, adding comments, importing/exporting form data, creating new pages using templates, connecting to databases and web services, etc. At first, the only way to enable these usage rights was with an expensive product from Adobe, so the potential was initially not realized.
    With the release of Acrobat 7, Acrobat users were able to add some usage rights, such as commenting. While this was a welcome addition, folks still wanted to be enable forms to be saved with Reader. Finally with the release of Acrobat 8 Pro, users were able to enable forms to be saved with Reader, but it came with licensing restrictions. In short, if the licensee distributed the form for more than 500 recipients, the licensee could use data from no more that 500 copies of a particular form that was returned to them, including hardcopies. This was great for forms used inside of an orginization, but not so great for forms that needed to be used by the general public. Still, it was a very useful feature for a majority of businesses for internal forms, the vast majority of which have fewer than 500 employees.
    Acrobat 9 or 10 didn't change things. Adobe still wants to capitalize on this market, which certainly is not a bad thing for Adobe and their stockholders. The US IRS forms have long been saveable with Reader because they licence Adobe Reader Extensions, which provides revenue for Adobe.
    Note that some third-party PDF viewers allow users to save filled-in forms whether or not the documents have usage rights. Such software has a different marketing model than does Adobe Reader/Acrobat, and rides the coattails of Adobe by taking advantage of the popularity of PDF forms.

  • I have a fairly new mac book pro with retina display- I have not tried installing anything other OS on it. In spite of that yesterday when I turned it on, I got the error: no bootable device insert boot disk and press any key. what is the reason for this?

    I swithced it on by clicking on options when I start up and then clicked on Macintosh HD. the other option was a question mark and network drive.
    Is there a way to ensure it never happens again, what is the cause for this problem, if I need to uninstall some application, i am happy to do it as long as I know what is causing this conflict.
    many thanks!

    Something is not making sense here.
    You claim this is a brand new machine and you have not tried to install Windows or Boot Camp.
    Then why would you ever even go into System Preferences > Startup Disk and choose Macintosh HD? It should have automatically booted into Macintosh HD.
    You're probably going to have to reinstall Mac OS X.
